Booting Stacked Configurations
Once the switches have been connected to a virtual chassis, the next step is to manually power on the 
stack. The OmniSwitch switch does not use an on/off switch. The power cord is the switch’s only connect/
disconnect device. The power connector socket is located on the switch’s rear panel. For more informa-
tion, refer to “Rear Panel” on page 2-55.
To boot the stack, plug the power cord (provided) into the power connector socket at the rear panel of each 
switch in the stack. Next, plug all power cords, in rapid succession, into easily-accessible power sources, 
such as grounded AC outlets or an Uninterruptible Power Supply (UPS).
Note. Be sure to power on all switches in the stack in rapid succession; otherwise, switches may be 
assigned unintended stack management roles. Refer to Chapter 6, “Managing OmniSwitch 6850E Series 
Stacks” for detailed information.
The stack immediately begins the boot process. Allow a few moments for all elements in the stack to boot 
completely, then verify the status of all LEDs on the switch’s front panel. A successful boot for a stand-
alone switch displays the following LED states.
If any of the LED state differs from the states shown in the table above, refer to page 2-53 for more infor-
mation. Contact Alcatel-Lucent Customer Support if the LED state persists. For information on logging in 
and configuring your OmniSwitch stack, refer to the Getting Started Guide and OmniSwitch Switch 
Management Guide.
LED States for a Stacked Configuration
OK Solid green for all switches.
Blinking amber - Switch is operational but Auto-Configuration was not 
successful.
PRI Solid green for the primary management module; solid amber for the 
secondary management module; off for switches operating in idle roles. 
Detailed information for primary, secondary, and idle roles is provided 
in Chapter 6, “Managing OmniSwitch 6850E Series Stacks.”
PWR Solid green for all switches.
BPS Solid amber if BPS attached is failed and off when no operational 
backup power supply (BPS) is attached; solid green if an operational 
BPS is attached and operating normally.
Slot Indicator 1–8 (non-blinking), depending on the slot number assignment for each 
corresponding switch. See Chapter 6, “Managing OmniSwitch 6850E 
Series Stacks” for detailed information.
